4 C ims- 1 This invention relates to stackers and loaders, and is an improvement over the construction embodied in application Serial No. 623,067, filed October 18, 1945, now Patent No. 2,481,994 granted Sept. 13, 1949, to Raymond M. Ginder for Hay Stacker and Loader and over Patent No. 2,228,796, dated January 14, 1941, issued to William V. Warren for Stacker.

An object of this invention is to provide as an attachment for a hay stacker and loader, a hydraulic operator for the sweep which can be attached to present staekers and loaders as a substitute for the winch type operator.

Another object of this invention is to provide an operator attachment of this kind which will provide a three-torone ratio with the use of only a pair of single pulleys so that the necessary swinging movement may be obtained for the sweep.

A further object of this invention is to provide an operator attachment of this kind which includes a frame for securing to the base of the stacker and loader frame, a hydraulic cylinder fixed longitudinally of the frame with the side bars of the frame forming guides for the ram or plunger, there being an idler pulley on the remand asecond idler pulley depending below the-frame.

To the foregoing objects, and others which may hereinafter more fully appear, the invention consists of the novel construction, combinationand arrangement of parts, as will be more specifically referred to and illustrated in the accompanying drawings, but it is to be understood that changes, variations, and modifications may be resorted to which fall within the scope of the invention as claimed.

f a r f r we d co v r nt ide bare ll connected together at their rear ends by a p ate. !2 and t eir or ard. er d v gent en s. by mea s f: a. conne t n ba a 13. The side members l l are also secured to a shaft. or axle housing I4 and wheels ii are disposed at the outer ends of the ax hou in A- The side. members II also hav extendin tbereb w eli. an intermediate connecting bar 16 and a pair of forwardly convergent bracing bars I! are co n. nected be ween he. nte me i, lie, p tions e the side members H and the, forward connecting bar 13.

The, stacker and loader includes a substantially inverted veshap d sup er-t ns membe '8 1 he. upper end of which a sweep structure l9 s rock ably mounted. The sweep structure H1 is, adapted to be vertically adjusted by means of an-adjustingbl 20 Which is trained a t an id e p l er- 2l carried by the sweep structure l9 adjacent. the rear end thereof. The sweep structure I}! is vertically adjusted by means of; a hydraulic adlu or erati at achment hi c udes; a frame 22 formed of a, pair of; angle bars 23 con: nected together at their rear ends by means Of; a connecting angle member 24, The frame bars. 2 3 are also connected together forwardly of the rear ends thereof by. means of a pla T QlWfiJ'QJ pertiqns of the bars 23 en a e we: e p a transverse bar [3 and are secured thereto bymeans of a pair of upstandi s members 2-5.- which are carried by an angle member 43 fined by. bolts 43 to angle member 13. Frame membersgi; have fixed thereto lugs 44, and 1 8s 26 are sex cured to lugs 44 by bolts 45. The frame bars 3; are disposed on a downward and rearward inclination as shown in Figures 2 and 4 and are secured at their rear portions to transverse mem her It by means of vertically disposed angle mern; hers 21. A hydraulic cylinder 28 is disposed between the frame bars 23 being fixed at its rear end on angle member 24 by means of a U-bolt 29. The cylinder 28 is also fixed on the plate by means of a U-bolt 30;. The cylinder 28 has slidiable therein a piston or ram 3| which has secured to its outer end a plate or head 32. A sheave block 33 embodyin a sin l pul 3 is s cured t extends ferwer l 9f relate and... His,

3 trained over pulley 34 and extends downwardly and rearwardly therefrom.

The connection plate 25 has dependingly secured thereto a second sheave 35 embodying a single pulley 36 and the cable 20 extends partly about pulley 36 and from this pulley extends forwardly and upwardly as indicated at 31. A round bar 38 is secured to the lower edge of plate 32, cable extension 3! engaging under the bar 38 and then extending upwardly and is secured to a bolt 39 carried by the sheave block 33.

The frame bars 23 form a guide for the ram 3| and in the present instance the frame members 23 have one side thereof extending inwardly as indicated at 40. The plate or head 32 has extending laterally therefrom slide bearing 4| engaging beneath the horizontal slides 46 of the guide members 23 so that the ram 3! will be relieved of any upward strain caused by raising of the sweep structure l9 when the latter is loaded.

In the use and operation of this device the hydraulic attachment herein disclosed is designed as a substitute for the mechanical sweep operator which is used on stackers and loaders at present available. It will be understood that this bydraulic operator may also be incorporated in a new sweep structure. The frame structure 22 is secured within the base frame it] being secured to forward transverse bar 23 on the upper side of this bar and secured to intermediate transverse bar IS in depending relation with respect to this bar. The cylinder 28 is connected to a source of fluid pressure supply and when it is desired to raise the sweep, ram 3! is moved forwardly thereby increasing the length of the loop between the sheave assemblies 33 and 35. Due to the fact that sheave assembly 35 is carried by a fixed portion of the frame and sheave assembly 33 is movable and one end of the cable 28 is secured to the sheave assembly 33, there will be provided a three-to-one ratio so that the cylinder 28 and the ram 3| may be made of relatively short length.
